High–Performance Silicon–Gate CMOS
The MC54/74HC563 is identical in pinout to the LS563. The device inputs
are compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
This device is identical in function to the HC533 but has the Data Inputs on
the opposite side of the package from the outputs to facilitate PC board
layout.
These latches appear transparent to data (i.e., the outputs change
asynchronously) when Latch Enable is high. The data appears at the outputs
in inverted form. When Latch Enable goes low, data meeting the setup and
hold time becomes latched.
The Output Enable input does not affect the state of the latches, but when
Output Enable is high, all device outputs are forced to the high–impedance
state. Thus, data may be latched even when the outputs are not enabled.
The HC573 is the noninverting version of this function.
